IMPROVEMENT IN CARDlNG-ENGINES.

Specification forming part of Letters Patent No. 50,377, dated October10, 1865.

To all whom t may concern:

Be it known that I, HAMILTON L. MoUL'roN, of Camden, Camden county,'NewJersey, have invented certain Improvements in Oarding-Engines, and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, and tothe letters of reference marked thereon.

My invention consists of a revolving drum or cylinder, provided withcombs, caused to operate by stationary cams and springs, substantiallyin the manner described hereinafter, in combination with thedofting-cylinder of a carding-engine, for the purpose of stripping fromthe said dofng-cylinder a more uniform sliver of fibers than can beobtained by the use of the ordinary strippingdevices, the wear and tearof the cardingengine being at the same time`mucl1 reduced by theapplication of my improvement.

My invention further consists in the combination of the saidstripping-cylinder, dofflngcylinder, and a tube, the whole being causedto revolve in the direction pointed out hereinafter, so that a strongand regular sliver may be produced.

In order to enable others skilled in the art to make and usemyinvention, I will now proceed to describe its construction andoperation.

On reference to the accompanying drawings, which form a part of thisspecilication,Figure l is a side view of sufficient of a carding-engineto illustrate my invention; Fig. 2, a sectional plan of Fig. l; and Eig.3, a transverse section of the stripping-cylinder, drawn to an enlargedscale.

A and Al are the opposite side frames of the machine; and B, thedofng-cylinder, the shaft C of which turns in suitable boxes, a a, onthe said side frames.

Near the front end of the machine is a shaft, D, to which is secured acylinder or drum, E, composed of the circular ends or heads d, con.nected together at their peripheries by slats c. The shaftD projectsthrough and turns in the cams F, each cam having a proj ection, f, whichis secured to a suitable box, b, on one of the side frames.

In the cylinder or drum E are a number of narrow longitudinal slots, x,(there being four in the present instance,) each slot being such as tocontain one of the combs h, and permit the same to slide freely towardand from the shaft D. Each comb has at each end a projection or pin, i,carrying a roller, j, the several rollers being caused to bear againstthe peripheries of the cams by springs m, (shown in dotted lines, Fig.2,) there being in the present instance one spring to each comb, one endof each spring being secured to the heads or slots of the cylinder, andthe other end being turned down through a hole in the comb. rlhe camsare of such a form and the combs and drum or cylinder are of suchdimensions that when one of the combs arrives at the pointy its serratededge shall project outward from the face of the cylinder to a distanceof about fivesixteenths of an inch, but on passing from the pointy shallrecede into the cylinder and remain there until it again approaches thepointy; in other words, the combs remain drawn inward from the face ofthe cylinder at all times, excepting when approaching and leaving thepoint y.

A tube, H, is caused to revolve in a box or bracket attached to one ofthe frames, this tube being in a proper position for receiving thesliver as it is stripped from the dofngcylinder B. This cylinder and thetubeH may be driven in the direction of their arrows by any suitablesystem of belts or gearing, but I prefer in all cases to drive both fromthe shaft C, so that e the doffing-cylinder, tube, and stripping-drummay operate in unison. As the dofting-cylinder revolves in the directionof the arrow the fibres collected in the card are stripped therefrombythe combs of the revolving cylinder and leave the card in the shape ofan uniform sliver, which passes through the revolving tube H.

A most important feature of myinvention is that each comb during onerevolution acts with stripping effect on the dofng-ca-rd for a verybrief time, and that each comb always remains withdrawn into thecylinder, excepting during its brief action. Hence there is nopossibility ofthe fibers being carried round. At the same time thesliver is uniform and perfect.

Another important feature of my invention is causing the dofingcylinder,stripping-cylin` der, and tube A to revolve in the direction of thearrows, as by this arrangement the fibers are stripped from the card ina direction the same, or nearly the same, as that in which the sliveristwisted bythe revolvingtube. Astrong sliver is thus produced. In fact,the fibers, as they are stripped from the Cardcylinder, are

rolled during the stripping process in the direction in which they areafterward twisted by the tube.

It will be evident that by the substitution of the revolving stripperfor the ordina-ry recipmeeting comb the weer and tear of the engine ismuch reduced.

I do not desire to confine myself to any speciiic number of combs or tothe precise devices described for operating the said knives; but

I claim as myinvention and desire to secure by Letters Patent- 4 1. Therevolving drum or cylinder, with the combs h and the springs m, or theirequivalent,
